To all whom it may c'onceen Be it known that 1? J F. Ft/02 71102, a citizen of the United States, residing et Chio in the county ,of Cool: and State of have invented a certain new and imigi'ovement in Side Bearings for lmy-Cars which the following is a teale211 concise and exact description, iei'ei-ence being bad to the accompanying clmwiiigs forming pert of this soeciticzi- My invention relates to improvements in bearings for railway c -s. e object of 'lIlVBIliZlG-Zl is provide sidelaeeiings liming resilient members of comparatively high shock absorbing capacity, and capable of eilicient automatic edjustment to each other of the bearing parts. the accompanying drawings Figure 1 s eiev on of side bearings shown in 1.2.06 between tile upper ar d lower bolsters "f o ilroad c111. 31g. 2 is a perspective broken swag), of the lower is a perspective view of the i is; a perspective View of one roliers bearings. Fig. 5 is a perspective View 01": the

The lower side bearing .12 comprises an enti-frictioni'oller 13, and adjustable cradle 14, springs therefor, e cradle frame 16, and en inclosing base casting 17. The :mti-f1-iction roller 1?, may be of any suitable form, a cylinder preferrec and pro vided at either end with trunnions l8, 18, which engage in the bearings 19, 1!), which are smured in the openings 29 20., in either end of the ci'adle 1e. The credll lie is provided on its upper side with recess 21, preferably conforming in contour to the ad anti-friction roller, having st eitliei which secures the roller At either side J midway between its ends i tide/l with a side trunnion Mimics. rests even an spring is flat, and is preferably 1 oppositely Speeifieetion :22 Letters Eetent.

The cradle frame 16 is preferably of a general rectangular shape, end is provided with an opening 25 Within which the cradle R rests the opening being of a size and shape adapted to permit oscillations of the cradle therein so that the antifriction roller 13 journaled in the cradle on movement of the can bolsters ed iust itself to engage with its entire length the bearingfece ll: of the upper side bearing.

Lugs 26, 26 provided at either end oi the cradle firmee are iiiliiififid to tl'ii'oogh their; means to secure the totlie base casting 1?. The cradle mine is pi'ovided at either side wltl a flange 27 flanges substz nnally parztliels in length the sh ll-friction roller 1.3 when the some is in its normal position, and each forms a seat for one of the spring; members 15.

The inclosizig base costing" 17 surrounds the cradle 14 and its frame 16, and on either side forms with the flange 27 and the shoulde of the cradle frame a recess 29, housing a spring 15. At either side this recess Each of said has oniipwzu'dly enlarged portion 30 to oei'mit the movement of the trunnion 23 of 1 too cradle l itherein, and to secure the cradle accidental displacement. The inclosing base cast-mgl? is provided with image at either end adapted to pass over 3 the flange 26 of the cradle frame, and KJQZ" fomtcl to receive rivetsor other suitable means of securing it to the bolster By reason of the resilient iriounting of tlie.
